Public bug reported: Summary: * libu2f-udev is not installed automatically, and after upgrading systemd it has lost its udev rules for U2F devices. * installing u2f-host (which pulls in libu2f-udev) doesn't seem to be enough to get it working either, had to manually reload the rules
Long version: I upgraded from XUbuntu 17.10 to 18.04 daily build for testing. Previously I was able to use a Yubikey U2F device with Chromium and Firefox, however after the upgrade no U2F device was detected, the browser just timed out the U2F detection. I installed u2f-host to debug the problem further but it told me that it couldn't find any U2F devices. I looked in /dev/hidraw* and my user couldn't access any. Running this and repluggingt the device fixed the permissions: sudo udevadm control --reload-rules. It looks like that systemd used to have udev rules for U2F devices but they got dropped recently, pointing to libu2f-udev: https://salsa.debian.org/systemd-team/systemd/commit/655e466caf37af36f527d42f164901b658203a2d Which is fine, except libu2f-udev is not installed automatically: libu2f-udev Reverse Depends: libu2f-host0 ubuntu-mate-desktop ubuntu-mate-core ubuntu-budgie-desktop libu2f-host0 Reverse Depends: libu2f-host-dev u2f-host pamu2fcfg libpam-u2f This seems wrong, individual desktop environments shouldn't bring this in, either the applications that use them (firefox, chromium) should recommend it, or a package common to all desktop flavours should pull it in. Please make libu2f-udev automatically installed as it was before when it was part of systemd, and reload the udev rules when it is installed. I'm filing this bug against systemd because the package that broke the behaviour was systemd, when udev rules got dropped from it the other packages' dependencies should've been updated so that the rules are not lost.
